The lighting requirements of an industrial facility are being
met by 1000 40-W standard fluorescent bulbs. The lamps are close to
completing their service life and the facility is examining
replacing them with 34-W high efficiency bulbs. A standard 40-W
bulb costs $1.77 each and a high efficiency 34-W bulb costs $2.26
each. The facility operates 8:00 AM to 8:00 PM every day of the
year, and the lamps are kept on during all operating hours. If the
cost of...
